Projectile motion with air resistance using Euler's method

Calculate the trajectory of our canon shell including both air drag and reduced air density at high altitudes so that you can reproduce the results in Figure 2.5. Perform your calculation for different firing angles and determine the value of the angle that gives the maximum range. //what are the speed and angle of the canon ball? using 700 m/s and 30,35,40,45,50,55 degrees
